Application filed May 17. 1907- Serial N0- 374.213-

' Patented Nov. 19, 1907.

To allwhom it may concern.

Be it known that I,- Isrnon Krrsnn, citizen of the United States residing at Philadelphia, in the county of lPhiladelphia and State of'Pennsylvania, have invented certain new resistance these movements are greatly retarded. The records therefore cannot reroduce the voice in its natural amplitude. t is the aim of my invention to obviate these difliculties.

As it is necessary to illustrate some means, whereby my invention may be carried out, I

have illustrated in the accompanying draw-- a simple arrangement to produce the undetails of the arrangement may differ without departing from the scope of my invention.

- In-the' drawing, Figure 1 is a cross section of a vrecording mechanism attached to the vibrating diaphragm. Fig. 2 is a plan view of part of a recor In Fig. 1, 1 is the mouth piece; and 2 the .vibrating dia hragm connected to the guide 3. This gui e is yieldingly guided by.the lever 4 supported at 5 by the projection 6. 10 is a reservoir containing the fluid 9; 8 a valve to open or close the orifice of saidreservoir; 111 are the means to force the fluid out of said reservoir; 14 is a fiexibleconnection connecting the orifice 7 with the reservoir 10; 12 is the material adapted to have deposited thereon the opaque line; and 13 are the recording lines.

In experiments, I found that it is best to produce the line out of diluted ink of the variety known in commerce as india mk and enerall used for'the production of drawings. or the material on which the .line is deposited, I found that glass answers the purpose best. It is obvious that the glass plate has to bemoved in the usual manner and I have not illustrated the means to move this plate, because such means are well known to persons versed in the art.

After the record is produced in the manner aforesaid, the plate is subjected, preferably, to what is known in the art as the photo engraving process, whereby a negative may be produced in suitable metal and wherefrom the copies may then be reproduced in any desired manner.

llaving now described my-invention, what I claim as new and desire to secure by Letters Patent is 1. The method of reproducing sound waves in permanent records,which consists in causing a fluid, opaque to the rays of light, to be deposited in accordance with the vibrations of a diaphragm actuated by said sound waves on a material transparent to said rays of light.

2. The method of producing sound records,

which consists in causing to be deflected the flow of a fluid 0 aque to the rays of light, in accordance witli the vibrations of a diahragm, and causing the so deflected opaque fluid to be deposited on a solid surface transparent to said rays of light.

' 3. The method of producing sound records, which consists in causing a material, colored so as to be opaque to the rays of light to be deposited on a transparent surface, in accordance with the vibrations of a phonographic dia hragrn, and causing then to be produced apl otographic copy of said deposited materia 4.. The method of producing sound records without actual contact of a stylus connected to the diaphragm, which consists in causing said stylus to guide the orifice of a reservoir containing an opaque fluid, causing said fluid to be de osited on the surface of a transparent materia and causing the so roduced record to be reproduced with the aid of the photogravure process.

In testimony whereof I aflix my signature in presence of two witnesses.
